1. PHYSICS AND THE LIFE SCIENCESIFNOTHINGELSE,MYSTUDENTSSHOULDLEARN…1.A physical model of a system is a description focusing on its most significant properties. Thedescription is built using observable phenomena, has a minimum number of assumptions,and should have predictive power.2.The accuracy of a measurement refers to how close it is to the accepted or correct value ofthe parameter being measured. The precision of a measurement refers to how repeatable themeasurement is, in other words how close different measurements of the same parameterconducted under identical conditions, are to each other. In general, the accuracy andprecision of a set of measurements are independent of each other.3.An order of magnitude refers to a rough numerical estimate of a physical quantity which isaccurate to within a factor of 10, or to within an order of magnitude.4.Dimensional analysis is a mathematical procedure in which information about relevantphysical variables in an equation can be obtained through manipulation, by equating thephysical dimensions of both sides of an equation.5.Scientific notation is a method of expressing very large or small numbers in a convenient andcompact fashion, also displaying all the relevant significant figures. It is very useful whenmaking order of magnitude estimates.6.Special mathematical functions such as the trigonometric functions, the exponential andlogarithmic functions, the square root function, and others, must always have dimensionlessarguments.LEARNINGOBJECTIVESStudents should be able to:Describe what a physical model is. (understand)Describe the characteristics that a good physical model must possess. (understand)Describe how significant figures are used in basic mathematical operations. (understand)
